One oftheprpfoses 'o f the present inventionis thetfil ingreplnishmentmay be effeetedhpon .breakngeor failure o filling,

` '-and should s uchhreakage .or failure occur4 q A 'a'. plural numberoftimesin succession, to iB thereuponstop the loom. It is also a featureA'of the'fp'resent 'invention vthat upon A a breakage or failure -offilling, thel'oom'may e bc stoppedat once; andto theseends, means A areprovided for controlling the actuatorv 61, :l as will'now be described.

In' a. suitable slideway formed. in the {illing -fork carrier or slide56, isthe' slide-har 66, Fig'. 8,; on which is detachably mounted Vtheblock 67 As shown inthe present 'form '35 of the invention, the hloclr67 is --provided with pins 68, which. engage suitable recesses in theslide-bar 466, the construction being such that n on movement of `the'slidebar the block -6 will be moved, .and yet the 40 block .67 may bereadily detached from its connection with the.slidebar.` It is these twoparts acting' in conjunction with the actuator 61 which select,accordin" to the requirements, whether .the loom 1s to be 4 5 `stopped-or the lling replenishing mecha nism o erated.

- In t e bottom of the slide-bar ,66 is pro- '."vidednvl series'ofnotches o r teeth 69, said notches 4being preferably thr ee in number,-66 asin'dicated, but any other 'desired number maybe' employed.Pivot'ed. at 70. in-a suitable notchor recess 71 (if-the Iplete-.151,.is a. qpaivl "7 2"norrns,lly;nnder the' infiueneej of .a

'ff'.j spring 76, Fig. 4'8, tending', to -move'the end' 'denteldisturbanceofits positron by 'vibration of'thegloom',.t' is providedwitha' recess "a6`Qj74, Fig. 9, in whieh-i's-seated'a light spring 75adapted to bear against one of the guide wells between which the slidebar moves.

.Securedto the bottomof the filling fork carrier5 6` is aplate `'T6having an opening 77fthrough'which the end of the pewl 72 is adapted'toproject and engage one of the notches in the slide-har positioned abovethe 'same, as the filling fork carrier moves to the front, The endportionsof the bloclr 6T are preferably inclined, as shown in Fig, 8,

and the actuator 61 is provided with a toe 76 adapted to cooperate withsaid. block.

InFig. 8 the parts are-shown in the position they occupy when theiillinv fork has detected an absence of filling and the hammer 49 isabout to engage the filling fork' to move the lling fork carrier or4slide 56 -to the front. As the carrier 56 is thus moved, the opening 77permits the pawl '72 to en gage the first tooth or notch in theslide-bar 66. and prevent .further movementl of the .slide-bar to thefront as the carrier 56 completes itsv frontward movement. The actuator61, on the occurrence of first breakage or failure of .llling,therefore, is heldjinraised position, and its end 62 engages the-'zrend' 63 of the arm 10 and initiates filling replenishment.- Should thefilling replenishing' operation be properly effected and the filling beproperly laid on the next detecting beat', the filling forli carrier 56would not be'moved tothe front, but the hammer L9 nmuld then engage therearward end of the slide 66 and move'it to initial position.'

Should, however, the Viilling not have been.

properly replenished, or' have broken or failed -n the next detectingbeat, then the iillingfork slide 5G would again be movedto the frontbythe weft hammer, and the pawl 7 2 would pass through thc opening .77und engage the second one of the notches in the slide-bar 66 as thefilling carrier V56 moves' tothe front in completing its forwardmovement. Since the' actuator. 6l is still held raised by lpliebloclr'67, filling rplenishmentwould e .eii'ected on such. secondfailure of iilling. Should a thirdfaill vure'oi filling-cocer, the pawl72 would engage the-third no teh in the slide-bar 66 and.

a'third cycle o vvoperation be negotiated, which -wouldrresult ,inmoving the slide-bar so far rearward as'to carry theblock .67 from underthe toe- '7S-oi the actuator l61 and `allo'wsaid actuator to swing.downward out'of the plane of the end. 63 of theup- ,wardly-extendingarm 10 and into position to engage the end 65 of the shipper lever,

whereupon the next or fourthdetecting beat or frontward movement of' thefilling fork carrier 56'would effect loom Stoppav e:

The loom'ha-ving been stopped in t e manner stated, nd the operativehavingfagain started the oom with a properly threaded' shuttle, and atlling thread being properly laid, thehmmer 49 on its first beatup 'orrontward movement, Willimpinge (in the rearward end of the slide-barandmove it in the slideway of the filling carrier 56 to initial position,as indicated in Fi'. 8. The sllde-bar 66 has been indicated as invase?provided with three notches 69, but obviously the number of notches maybe varied,A and vthe number of filling replenisliinents due to fillingfailure be varied prior to c fecting Aloom stoppage.

As liereinbc'lore noted, it may he desircble Y et times to operate theloointo eiiect filling replenishment prior to completejenliaiisti onofthe filling and to eilect loom stoppagept once upon u. single failureor brealrage'l'cf filling. To inauguratoV this operation, i s

filling, and to effect suoli replenishment a plural number. ci' timesbefore stoppingv the loom, in which case it'is necessary on y` to removethe bunter 37. Should itbe desired to temporarily suspend both thefeeler and the filling fork replenisliing; operations, the

.bunter 37 and the block 67 can be readily removed, whereupon the loomwill operate es an ordinary loom, and stop on the occur4 rence offilling breakage or failure,
